Vehicle light outline quality detecting method based on three-dimensional laser scanning

The invention relates to a vehicle light outline quality detecting method based on three-dimensional laser scanning. The method can effectively solve the problems that the efficiency is low, the measuring accuracy is low, the reliability is poor, and product quality cannot be ensured in the artificial measuring process. A three-dimensional laser scanning measuring system used for vehicle light outline quality detecting is composed of a PC machine, an industrial robot and a 3D laser sensor, and vehicle light outline data scanned by lasers is acquired; the vehicle light outline data scanned by the lasers is taken as a processing object, through identification of vehicle light boundary points and standard vehicle light mold boundary points, a standard vehicle light mold is taken as reference,three-dimensional outline data of a vehicle light is contrasted with standard three-dimensional outline data of the vehicle light, and the vehicle light outline quality is detected. The method has the advantages of being nov
